What are some potential pitfalls when sorting strings with numbers in PHP arrays?

When sorting strings with numbers in PHP arrays, a potential pitfall is that the sorting may not be done in a natural order, as strings are compared character by character. To solve this issue, you can use the `natsort()` function in PHP, which sorts the array in a natural order that is more human-friendly for strings with numbers. 

$strings = ["item1", "item10", "item2", "item20"];
natsort($strings);
print_r($strings);
